What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window mastic for homes and businesses in Egerton
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. We work on window sills, composite doors and aluminium frames, and common reasons people get in touch are leaking joints at the ends of sills and black, perished sealant on frames.
In a village or hamlet like Egerton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Air rooms to keep condensation down around windows
- Clean frames with a soft cloth and soapy water
- Keep solvents and bleach off the sealant
- Keep timber frames painted
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
What window mastic looks like in Egerton
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Egerton Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Pluckley station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. Somewhere as small as Egerton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

FAQs for Egerton
Do you cover smaller places like Egerton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Pluckley station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can new window sealant be painted?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How we quote for window mastic
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- The type of sealant required
- Access and height
- How many areas need sealing
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
- Where the property is
- If someone has resealed it before
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In a small place like Egerton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Do you need window mastic in Egerton?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Whistling draughts around closed windows
- White mastic on grey or black frames
- Cracked internal joints between frame and plaster
- Mastic that has split away from the wall
In the older streets around Church of St James, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
